Hi all, had a service some weeks back and since then my economy has risen noticeably from about 8.2 l/100 to currently 11.1. My driving pattern did change about the same time, I was doing about 40km a day with mostly 70-80 zones (but constantly fanging it) plus toodling around near home, whereas since the service I'm no longer doing that 40k, but just driving around my local suburban area (and less right-foot heavy). It's hard to compare apples with oranges but is that enough to change economy so drastically? I would always giggle about being able to thrash it and still stay around the 8-ish l/100 mark. Just wondering what people think. I know there's a few variables in there. One constant is same servo and petrol, Caltex 98.
